I do not think it will work just by changing plugs. It is not going
to have the correct scan codes. If it is what I think it is, the
"monitor" was actually a terminal. The machine you have probably
used a serial connection to the terminal, and the terminal send
ASCII code to the computer. If you had the "CRT" part, you could
probably hook it to a serial port and use it under Linux. (I have
done that with a few "smart" terminals...)

The keyboard may generate modified ASCII code, or its own codes that
the firmware in the terminal translated. A common method was serial
communication with 7 bit ASCII code, and special functions if the
8th bit was set.

What you MAY be able to do is convert the keyboard so it will
connect to a serial port. But it is probably going to be more
trouble then it is worth.
